my apologies for not addressing this earlier, I had some pressure at work and urgent family issues to attend.
I won't my special filter didn't caught these mails, will recheck it.
for now, odroid c2 need that compiler because it uses the vendor's forked uboot.
as of uboot 2017.05, there is support for this board in the official tree. afaik, bumping uboot to that version remove the gcc restriction but unfortunately bumping the version will render the board unbootable.
there is a need to specially sign the uboot image.
I'm working on such support but up until I wasn't able to get the board to boot. due to the reasons mentioned above, I was not able to work on this in the past 3 weeks.
I hope to be able to resume work on this an finish soon.

Dagg.
